Said base is prefdetermined edgewise abutting relationship to erably rectangularand bears on its upper surform a rectangular arrangement having vertical, face a series of coorthogonal lines 2 forming recl0 horizontal and diagonal rows of indicia in which tangular spaces of approximately the same area the sum of the indicia displayed along each row as the area of the respective defined areas on is the same as the sum of the indicia displayed the elements in which the counting indicia are along other parallel rows. formed. g 1

It will be seen that elements of the series and be received in angular each of these elements consists of a number of recesses or notches therein.

It should beclear that numerals, either Roman or Arabic, maybe used instead of the spots shown as counting indicia.

The elements maybe made in different forms so long as each includes more'than one complete piece analogous to a domino piece. It is possible that the invention may be varied otherwise than in this particular and, without restricting myself unessentially, I claim:

A device of the character described comprising a support having thereon side by side rows. of clearly. defined visible rectangular areas of uniform size, a series of angular elements each having portions extending angularly from each other and each element being of the same area as a plurality of said areas on said support and having edges arranged to register with the edges of said areas on said support covered by the respective elements when the respective elements are properly placed, and guides in connection with a plurality of said elements indicating the proper lateral position of said elements having said guides with respect to the remaining elements, all of said elements having edges adapted to be placed in abutting relationship to form a rectangular assembly of all of said elements covering all of said rectangular areas on said support and said series of elements having on their upper sides rows of defined areas containing counting indicia which in the proper arrangement of the elements are of the same sum in one row as in any other
